To all whom it may comm.-

certain new and useful Improvements in Adapters for Sheet-Metal Piping, of which thefollowing is a specification.

' My invention relates generally tosheet metal pipe construction and more particularly to an adapteror reducer to be u sed in connection with stove pipes forconnectmg' fines of different dimensions iand of the same or different cross-sectional shape; as}

for instance, to connect the outlet opening in a stove, which is usually elliptical shape," with the conduit or 1 pipe leading :to the discharge opening into the chimney, or" to con nect sections of pipeboth ofcircular cross section, but ofdiflerent dimensions. While my invention is especially adaptedforthe purposes justmentioned, it, ofcourse, will be obviousto others thatgthe principles are; capable "of being incorporated in tall sheet metal pipeysuch as fur11ace pipes,hot air conduits, andthe like, without materially affecting the structure 'or' departing from the principles involved, and such uses and 1 such modificatlons as may be. made arecontemplated as included within the scope of my claims. l 3

' 'In joining a smoke pipe which is round in section to the smoke outlet of the stove, which is usually elliptical, it is thewpra'ctice to simply compressior. distort one end of a stove pipe until it shapes-onconforms to the smoke outlet opening of the stove. A

round conduit "is a-l'nuch more efficient conduit and after connectlon with the stove has been made'a round pipe of smaller diameter than is necessary in makin the connection can be used to advantage, t ereby effecting economy of material necessary in making the joint and also an economy in the space necessary for installation which is very often of vital importance.

The principal object of my invention is the production of a device for connecting runs of pipe or an opening and a pipe of different dimensions and the same or different shapes. Devices for connecting runs of pipe of different dimensions, known as reducers, are in use, but the peculiar characteristic of my device lies in the'fact that one end thereof and the tapered portion are I l s ecification of Letters Patent. 1 i

made from a single integral piece of sheet metal which permits the end inquestion to befittedto a large variety of shapes of openings, as Well as fitted to pipes of round or circular section. My reducer can also be muchmore economically made, as the amount of'work thereon is less than is required in producingsuch fittings of three pieces. A further object is the provision of areducer of'this character that is provided with suitable reinforcements in the shapeof indentations or inturned beads, whereby the excess metal at the juncture of the tapered and straight portions is disposed of and greater-rigidity is obtained; and a still further object is the provision of a suitable blank from which the lower portion of the section comprising both tapered and straight forms is fabricated outof a singleintegral sheet of metal. 1 V

F I prefer to accomplish the divers objects of my invention substantially in the'manner. and by the. means hereinafter fully described and as more particularlypointed out in theclaims, reference being had to the accompanying drawings which form a part of this specification, wherein-z- Figure 1 1s a vertical side elevation of an Referring more particularly 4 of the drawing, it will be observed the blank for the lower tapered and straight'portions .oftheadapter preferably comprises an in tegral flat sheet of metal, the body portion A whereof is preferably of a substantially rectangular shape, having its upper and lower edges curved slightly upwardly toward the center. The upper edge of the central rectangular blank, after describing the curves just mentioned, sweeps obliquely upwardly to provide edges 6, b of the lateral oblique ends B, B of the blank. The lower edges of the lateral or oblique ends B, B are substantially straight and inwardly extended V-shaped notches or darts C, C are cut in a convergin direction a distance slightly to correspon to the parallel portion ofthe tapered section.

In assembling the reducer, or, in other Words, forcing the structure above described,

6 to the upper edge of this blank by an optwardly extended bur or rib "2", extending around the blank and a cooperat or bead in the'dgof the collar. C, C are now closed by: overlapping: the edges thereof, as shown at 8 in Figs. 2 and 3',"an'd securing them in place by rivets 9;=so as 130' render the wallsoftliis part of the'" sec ti'on parallel" instead of tapered. Th'edoiver portion of this member ma'j'nnow be' com 15 pressed to form the elliptical outline 1 sh'owrr in* detail in Fig: 3 of the drawings,-: 'to'" permit its lower ed'geto fit th'e elliptical-shaped" openlngyfor the smoke flue .01 it may vbe-- pressed into a wound section?
